Sen. Claire McCaskill, D-Mo., said, “It feels like this is a very limited provision written for a very special person.”

The tax package would impose a new tax on investment income earned by some private universities and colleges. Sen. Pat Toomey, R-Pa., added a provision exempting certain colleges that don’t receive federal funds. Democrats said Hillsdale was the only college that would benefit.

Toomey defended Hillsdale as “a wonderful institution” and said other schools might qualify for the tax break, too. Toomey said a school that declines federal funds saves taxpayers “a tremendous amount of money.”

“I do understand that my colleagues on the far left do not have fond opinion of Hillsdale. But I do. I actually think it’s a wonderful institution,” Toomey said.

Sen. Jeff Merkley, D-Ore., proposed an amendment to strip the tax break for Hillsdale and it prevailed by a 52-48 vote.

Four Republicans joined all Senate Democrats in voting to adopt Merkley’s amendment. They were Sens. Deb Fischer of Nebraska, Susan Collins of Maine, Lisa Murkowski of Alaska and John Kennedy of Louisiana.

Democrats complained that some well-known conservatives have connections to the school, including Trump administration Education Secretary Betsy DeVos.

Graduates include Erik Prince, who is DeVos’ brother and the founder of the government contractor once known as Blackwater, and former Rep. Chris Chocola of Indiana. Chocola once headed the conservative Club for Growth, an advocacy group that Toomey also once led.
